The invention relates to the technical field of flue gas deacidification treatment, in particular to a flue gas treatment device and process for incineration flue gas double-dry-method deacidification. According to the device, calcium hydroxide powder and sodium bicarbonate powder can be scattered, so that flue gas in the reaction furnace is deacidified more sufficiently, meanwhile, powder blocks left on the inner wall of the reaction furnace can be scraped, the inner wall of the reaction furnace is convenient to clean, and the effect and efficiency of flue gas deacidification are improved. The device comprises a bottom frame, a mounting column, a reaction furnace and the like, two mounting columns are arranged at the upper part of the bottom frame, and the upper parts of the two mounting columns are rotationally connected with reaction furnaces. Calcium hydroxide and sodium bicarbonate powder are manually poured into the storage hopper, flue gas is introduced, the motor is started, the powder can be scattere
